CVE-2026-56345 Alta · 8.1 CWE-287 20/06/2026
AVideo - Arbitrary User Session Hijacking via Meet Plugin uploadRecordedVideo Endpoint
AVideo through 29.0 contains an authorization bypass vulnerability in the Meet plugin's uploadRecordedVideo.json.php endpoint that derives the target users_id from the uploaded filename without verification. An attacker with knowledge of the Meet shared secret can craft a malicious file upload with a filename containing an arbitrary users_id to invoke passwordless User->login() and establish an authenticated session as any user including admin. Attackers can obtain the Meet shared secret through path-traversal vulnerabilities or timing attacks against checkToken.json.php, then POST a crafted file to uploadRecordedVideo.json.php with a filename like '1-anything.mp4' to hijack admin sessions and gain full account takeover.
CVE-2026-56294 Média · 4.8 CWE-287 20/06/2026
capacitor-native-biometric - Authentication Bypass via Unvalidated CryptoObject in onAuthenticationSucceeded
capacitor-native-biometric before 12.128.2 contains an authentication bypass vulnerability where the onAuthenticationSucceeded() method fails to validate CryptoObject parameters.

CVE-2026-56080 Média · 4.9 CWE-287 19/06/2026
Cap-go - Authentication Logic Flaw in Enforce Password Policy
Capgo before 12.128.2 contains a flaw in the Enforce Password Policy feature: after a Super Admin enables the policy and successfully changes their password to a compliant one, the backend does not update the password-compliance state. As a result, the backend continues to treat the account as non-compliant and repeatedly forces password-reset prompts, permanently locking the Super Admin out of organization access (organization lockout / denial of service) despite valid authentication.
CVE-2026-50559 Alta · 7.5 CWE-287 19/06/2026
Authentication/Authorization Bypass via Advanced Path Normalization Vulnerabilities
Quarkus is a Java framework for building cloud-native applications. Prior to versions 3.37.0, 3.36.3, 3.33.2.1, 3.33.3, 3.27.4.1, 3.27.5, and 3.20.6.2, Quarkus HTTP path-based authorization policies can be bypassed using encoded semicolons (%3B) to smuggle matrix parameters past the security layer, and using encoded slashes (%2F) or backslashes (%5C) to access protected static resources. This is a distinct issue from CVE-2026-39852, which addressed only literal semicolon stripping. Versions 3.37.0, 3.36.3, 3.33.2.1, 3.33.3, 3.27.4.1, 3.27.5, and 3.20.6.2 contain a patch.

CVE-2026-49454 Crítica · 9.1 CWE-287 18/06/2026
Biblioteca SAML Relyra aceita assinaturas forjadas (bypass de autenticação)
Relyra é uma biblioteca de Service Provider SAML 2.0 estrita por padrão para Elixir e Phoenix. As versões 1.0.0 e 1.1.0 aceitam assinaturas SAML forjadas porque o SignatureValue não era verificado criptograficamente antes de a biblioteca retornar um resultado de autenticação bem-sucedido. A fronteira de confiança XMLDSig estava incompleta, pois :public_key.verify sobre o SignedInfo canonicalizado com C14N exclusivo não era executado contra a chave pública do certificado do IdP configurado, o DigestValue não era recalculado sobre o elemento referenciado canonicalizado e canonicalize/2 permanecia como um passthrough não utilizado no caminho de verificação de assinatura. O resultado era um caminho de aceitação baseado apenas na estrutura, em que a forma do documento e a rejeição de fontes de confiança podiam ter sucesso sem comprovar os bytes da assinatura. Um SignatureValue forjado contendo um NameID controlado pelo atacante podia ser aceito como {:ok}. Este problema foi corrigido na versão 1.2.0.
CVE-2026-11718 Crítica · 9.1 CWE-287 18/06/2026
Google MCP Toolbox for Databases: bypass de autenticação na validação do emissor de tokens opacos
Existe uma vulnerabilidade de bypass de autenticação no caminho genérico de validação de tokens opacos (validateOpaqueToken) do googleapis/mcp-toolbox. Quando o toolbox valida um token opaco por meio de um endpoint de introspecção OAuth 2.0 (RFC 7662), ele decodifica a resposta em uma struct introspectResp. No entanto, a lógica subsequente de verificação de claims (validateClaims) avalia a condição do emissor como a.issuer != "" && iss != "". Se a resposta de introspecção do provedor OAuth externo omitir completamente o campo opcional iss (emissor), a variável iss assume por padrão uma string vazia. Isso faz com que o bloco condicional seja avaliado como falso e ignorado silenciosamente. Consequentemente, a aplicação aceita tokens emitidos por provedores de identidade de terceiros não autorizados ou não pretendidos.
CVE-2026-11717 Crítica · 9.1 CWE-287 18/06/2026
Google MCP Toolbox for Databases: bypass de autenticação na introspecção de tokens opacos
Existe uma vulnerabilidade de bypass de autenticação no caminho genérico de validação de tokens opacos (validateOpaqueToken) do googleapis/mcp-toolbox. Ao verificar um token opaco não analisado por meio de um endpoint de introspecção OAuth 2.0 (RFC 7662), o toolbox decodifica a resposta em uma struct introspectResp em que o campo Active é declarado como ponteiro para booleano (*bool). O código rejeita explicitamente um token apenas se a resposta contiver o campo active preenchido com false (if introspectResp.Active != nil && !*introspectResp.Active). Se um endpoint de introspecção responder com um payload que omite completamente a chave obrigatória active, a variável interna permanece nil, fazendo a verificação condicional ser ignorada por curto-circuito. Como resultado, o Toolbox aceita tokens de autorização sem o campo «active», concedendo acesso a ferramentas protegidas e às fontes de dados subjacentes.
CVE-2026-48991 Média · 5.5 CWE-287 17/06/2026
XianYuLauncher: Legacy Microsoft account OAuth sign-in flow lacks PKCE and state validation
XianYuLauncher is a Minecraft Java Edition launcher. In versions prior to 1.5.5, sensitive authentication artifacts could be exposed during a user-initiated login under certain local attack conditions. Affected versions relied on a fixed localhost redirect URI without PKCE or state validation. Exploitation is most likely to occur when an attacker is able to observe, intercept, or otherwise interfere with the local authentication flow on the same device. This issue has been fixed in version 1.5.5.

CVE-2026-48117 Média · 6.8 CWE-287 17/06/2026
DroneAware's Improper Account Activation in Registration and SSO Flows Leads to Account Takeover
DroneAware is a drone detection platform. The centralized DroneAware server backing droneaware.io was vulnerable to an account pre-hijacking attack in which an attacker could register an account using a victim's email address with an attacker-controlled password before the victim completed account activation. When the legitimate owner later activated the account, either by clicking the email verification link or by logging in via Google SSO, the attacker-set password became fully valid, enabling silent and persistent account takeover without any notification to the victim. The vulnerability was fixed server-side on 2025-05-20; no user action is required. Node binaries and self-hosted detection nodes are not affected. There are no workarounds; the fix was deployed server-side and no client-side mitigation is applicable.

CVE-2026-48929 Alta · 7.5 CWE-287 17/06/2026
Rocket.Chat in versions <8.5.1, <8.4.4, <8.3.6, <8.2.6, <8.1.6, <8.0.7, <7.13.9, and <7.10.13 is...
Rocket.Chat in versions <8.5.1, <8.4.4, <8.3.6, <8.2.6, <8.1.6, <8.0.7, <7.13.9, and <7.10.13 is vulnerable to unauthenticated file deletion. The deleteFileMessage Meteor method permanently deletes any uploaded file by ID without requiring authentication. When called via an unauthenticated DDP WebSocket connection, Meteor.userId() returns null, causing the authorization check to be skipped. Execution falls through to FileUpload.getStore('Uploads').deleteById(fileID), which removes the file from storage and database unconditionally. File IDs are discoverable from public channel message payloads and download URLs.

CVE-2026-46705 Média · 5.3 CWE-287 10/06/2026
russh server userauth state is not reset when authentication principal changes
Russh is a Rust SSH client & server library. From version 0.34.0-beta.1 to before version 0.61.0, the russh server authentication path keeps internal userauth state across SSH_MSG_USERAUTH_REQUEST messages without separating that state when the request principal changes. RFC 4252 allows the user name and service name fields to change between authentication requests. The issue is not that such changes are invalid. The issue is that russh-owned authentication state, such as remaining methods, partial-success state, and in-progress method state, can remain associated with the connection and then influence a later request for a different (user, service). This is an internal library state mismatch. This issue has been patched in version 0.61.0.
